TALL-FORM TIE STRUCTURE.

Application filed September This invention, relates to a knock-down tie device for retaining tot-inst particularly concrete wall terms, in spaced relation and precluding the same from movement toward 5 or from e: ch other whi e the wall is heing poured or curing.

lhc invention has for it- 'ect to provide a tie device adapted for use in the erection of walls of various thiclmessea: one which is capable of heiug disassemhled when the wall retaining forms are removed: and oner the parts of which are, when emhedded in the formed wall. readily removed therefrom: to provide a wall tie structure capahlrt" rapid assembly and erection as the inoua'iare eo:- structed and disassembled when t e wall has cured without the necessity of can; oying skilled lahor, and which may he quickly set up when it is desired to use the some in the erection of other wall forms: t rovide a t e structure which consists of l nt: tew parts. is capable of quick adjustn'ient. an d the tie member of which is lineally tapered enahling the same to he readily driven from a formed wall at the time tl 1C mould forming members are removed.

The invention consists hroadly in a pair of anchor memhers for securing to the wall forming purlins and a connecting tie or men her lineally taper w, and releasahl held in lineally adjustable overlapping relation to provide a uniting tie for the anclr i memhers, there heing employed means to interlock portions of the tie to the anchor memhe s in their relatively adjusted position.

Vith the ahove mentioned and other ehieets in view, the invention consists in the novel constrm-tion and comtdnatmn of parts hereinafter descrihed, illustrated in the eccompanying dmwiugs and pointed out in the claims hereto appended: it heingunderstood that various changes in the form. proport ion. size and minor details of cousl'rmrtion within the scope oi the claims ma he resorted to without departing turn the spirit or sacrificing any of the advantages oi the invention.

Fig. (l is a view in stirrup In the drawings. wherein like characters of r r terence designate corresponding parts the numerals 1 indicate the huilt-up walls of the wall forming mouhh preferably constructed of wood and atlording between their faces a space 9 for filling with wall forming material, preferably concrete. The walls 1 are secured to spaced uprights 3, and these, in turn, are held by horizontally spaced purlins 4.

During the erection of the wall forms, the mould uprights 8 are extended upwardly, and those associated with the respective sides of the mould are united by the purlins 4. To the inner faces the uprights 3 are nailed the hoards or wall tormingmemhers 1.

r t intervals, as the height of the mould walls progress, means are provided to mainain the mould walls in their predetermined spaced relation to insure the construction of a concrete wall of uniform thickness. At the des intervals. and preterahly at predetermined horizontal levels in the construction of the forms, anchor members and 5 are secured to opposing purlius. with their body portion 6 in spaced parallel alignment. The anchor memhers are preterahly of flat st 'ap i'naterial, the respective rear ends heing angularly hent at 7 to project downwardly over the outer edge of the purlins, and said anchor members are preferably removahly secured in position on their respective purlins hy driven memhers not shown, which pass through apertures 8 The anchor members 5 and 5' are each formed on one end with a connecting member guiding collar or eye 9, and the member 5 is formed in its opposite side edges in rear of its collar with the recesses 10 for receiving the side walls of an interlocking wedge 11.

The wedge in the form of an oblong loop or stirrup, consisting of parallel side walls 12 and connecting top and bottom walls 13, the side walls having inclined rear edges ll formed with interned flanges 15 terminati short of the bottom wall and which ore adapted to hear on the end wall in end elevation of the locklma 16 of the recesses 10, with the forward edges 7 of the side walls bearing on the rear edge of the collar 9 of the anchor member 5, as in Fig. 2 of the drawings.

With the anchor members and 5 assembled, as above described, a tie member 16, preferably of strap materialv is moved longitudinally of the member 5, through its loop 9. The tie member 16 formed at one end with a stop flange 17 which contacts with the rear surface of the collar 9 of the anchor member 5. and is undercut, forming a shoulder 18, which is adapted to contact with the end of the anchor member 5 beyond its collar 9.

As in the drawings, the faces and side edges of the tie member 16 converge from the flange 17 toward its other end, and when in position, sa id tie member span s the space 2 formed between the wall forming members 1.

in positioning the tie member as in the drawings, the same may extend through aligned spaces provided between the meeting edges of the mould wall forn'iing boards 1, although apertures, not shown, may be cut through solid portions of the board to allow for the projection of the member 16 thcrethrough.

The free end of the member 16 is extended through the collar 9 of the anchor member 5 with the notched side edges 17 thereof overlying the body portion of the anchor member 5, as in Fig. 2 of the drawings.

During this adjustment, the stirrup 11 is in a raised position to admit of the reduced end of the tie member 16 passing between its side walls below the lower ends of flanges 15. When the adjustment is accomplished, the stirrup 11 is lowered, enabling the flanges 15 to pass downwardly through the notches 17. lying imn'iediately above the wall 16 of the recesses 10.

lVith the construction so assembled and with opposite ends of the tie member 16 releasably locked to the opposing anchor members 5 and 5, the wall mould sections are precluded from separating or being forced together by outside pressure.

After the wall has been formed between the members 1 and has set or cured for the requisite period, the stirrup 11 is raised to position the lower end of flanges 15 above the upper surface of the tie member 16. The securing member for the anchor member 5 is removed and an endwise blow is delivered to the free end of the tie member 16, which blow will, due to the tapered construction of the tie member 16, release the same from the formed wall and permit its withdrawal line lly from the wall thereafter the form members are removed and the anchor members 5 are removed from their associated purlins.

It will be observed that the contact of the flange 17 with one edge of the collar 9 of the anchor member 5 and the contact of the stirrup 11 with one face of the collar 9 of the anchor member 5, and the engagement of the stirrup flanges 15 in opposing notches 17 of the tie member 16, preclude the separation of the wall forms when pressure is applied between the adjacent faces of the members 1 hereof.

It will also be observed that the engagement of the shoulder 18 w th the end of the anchor member I, and the contacting of the flanges 15 with the walls 16 of the recesses 10, and the reception of the flanges 15 in the notches 17, with the anchor members secured to the purlins, preclude movement of the mould forming walls toward each other.

It will be observed that the present wall tie structure is capable of quick assembly and dist antling, is composed of but few parts, and that the tie member li'i thereof, due to its tapered construction, is capable of being readily removed or driven from a formed wall as its faces are released from the wall structure immediately on the tie member being moved the slightest distance toward its large end.

I claim 1. A knock-down holding device for wall forming moulds comprising a pair of anchor members, a connecting tie member detachably uniting the anchor members in adjustable relation, said connecting tie member being tapered toward one end provided with a lateral projection at one end for cooperation with one of the anchor members, and slotted atits opposite end for cooperation with the other anchored member.
